Citing Sources & Avoiding Plagiarism

How to avoid plagiarism and cite sources correctly.

APA Style Manual

Interviews, Email, and Other Personal Communication

No personal communication is included in your reference list; instead, parenthetically cite the communicator's name, the phrase "personal communication," and the date of the communication in your main text only.

(E. Robbins, personal communication, January 4, 2001).

A. P. Smith also claimed that many of her students had difficulties with APA style (personal communication, November 3, 2002).

Purdue OWL: APA Citation - Electronic Sources

In-Text Citations

Material from your paper that's from another source needs to be cited both in the text immediately after the cited material (in-text or parenthetical citation) and at the end of the paper in the works cited. However, if you mention information about the source in the text of your paper, you do not need to include that information in the citation immediately afterward.

For example ...

Example 1: Jenkins (2003) described the beginning stages...
Example 2: In the beginning stages... (Jenkins, 2003)
